Get on half hourly tariff if you can (example for the UK is Octopus Agile).

As long as you don't concentrate your usage between 4pm and 7pm, it saves a shitload of money over a regular tariff. The other day, they paid me to put the washing machine on.

There conclusion is shit, but doesn't the electrical grid require the amount generate and consumed to be effectively the same? I could see the difference being more of an issue as renewable become more prevalent, and we unfortunately cannot just turn off the sun when we don't need it.

Remember what Conservatives said about "not enough power"? I think that might be a lie
